Fabrication and Wettable Investigation of Superhydrophobic Surface by Soft Lithography李刚School of Mechanical and Electrical Engineering, East China Jiaotong University摘 要:The natural hydrophobicity of surfaces can be enhanced if they are microtextured due to air trapped in the structure, which provides the deposited drop with a composite surface made......
impedance electrodes with high stability, the chemical etching process was used to fabricate the copper electrode with a series of surface microstructures. By changing the etching processing parameters, some comparison experiments were performed to reveal the influence of etching time, etching temperature, etching liquid concentration, and sample sizes on the etching rate and surface microstructures......
